Liquid-evaporation-type heat radiator and manufacturing method thereof

Abstract

The invention discloses a manufacturing method of a liquid-evaporation-type heat radiator. The method provided by the invention comprises the following steps: setting a heat radiation plate and a heat conduction block which conducts the temperature of objects emitting heat to be separated; simultaneously arranging a heat conduction pipeline in the heat conduction block, wherein one section of the heat conduction pipeline is embedded in the heat conduction block, and the other section of the heat conduction pipeline extends out of the heat conduction block and is higher than the top end of the heat conduction block; adding and pouring liquids which can be evaporated into the enclosed containing chamber of the heat conduction pipeline; and then mounting the heat radiation plate on the heat conduction pipeline which is higher than the top end of the heat conduction block. According to the invention, the temperature of the objects emitting heat is utilized for heating the liquids which can be evaporated in the heat conduction pipeline, thus the liquids which can be evaporated are heated rapidly into evaporation gases and radiate through the heat radiation plate, and after the evaporation gases are changed into liquids which can be evaporated after the evaporation gases are cooled, and flow back to the lower part of the heat conduction pipeline for the next evaporation and heat transfer circulation. The method provided by the invention has the advantages of good heat radiation effect, small volume, lighter weight, easiness in manufacturing, lower manufacturing cost and the like.

Description

technical field [0001] The invention relates to a liquid evaporative radiator and a manufacturing method thereof, belonging to the technical field of air-cooled radiator manufacturing. Background technique [0002] At present, the air-cooled radiators in the prior art or the air-cooled radiators filled with heat-conducting medium (or cooling medium) generally fix the heat sink on the heat-conducting block used to conduct the temperature of the heating object. The radiator of this structure Because the heat sink and the heat conduction block are made as one, although it has the advantage of fast heat conduction, it is cooled by the outside air, and the heat conduction block is generally large in size and heavy in weight, so there is a large thermal inertia. In addition, if it is integrated with the heat sink, its thermal inertia will be greater, and it will be difficult for the heat of the entire radiator to dissipate into the air, even if a heat conduction medium (or cooling...

[0002] At present, the air-cooled radiators in the prior art or the air-cooled radiators filled with heat-conducting medium (or cooling medium) generally fix the heat sink on the heat-conducting block used to conduct the temperature of the heating object. The radiator of this structure Because the heat sink and the heat conduction block are made as one, although it has the advantage of fast heat conduction, it is cooled by the outside air, and the heat conduction block is generally large in size and heavy in weight, so there is a large thermal inertia. In addition, if it is integrated with the heat sink, its thermal inertia will be greater, and it will be difficult for the heat of the entire radiator to dissipate into the air, even if a heat conduction medium (or cooling medium) is added to the heat sink of this structure , the heat conduction medium (or cooling medium) is also difficult to play a role, so the existing radiators generally have the disadvantages of poor heat dissipation, large volume, and heavy weight
